Project Summary:Demonstrate and assess energy and demand savings impacts of the following technologies and design strategies at three sites in northern and central California: -Variable air volume (VAV) for exhaust hoods, including applicable controls, -Makeup introduced through backwall supply...

Project SummaryEvaluated the potential energy savings of a combination of lighting system replacements and a new lighting installation in three different spaces on the LA County Internal Services Division campus. In the welding shop, probe start metal halide aluminum canister fixtures were replaced...

Project Summary:The current project uses 100% uplight luminaires installed with dimming ballasts and 5000K lamps. Users have the ability to adjust the lighting levels to match their own preference. Dimmed levels and energy usage are metered for individual users and compared to individual users...

Laboratory cold storage solutions such as refrigerators and freezers are critical to keeping valuable reagents and samples safe in biotechnology, pharmaceutical, university, government, and healthcare research laboratories. High performance laboratory grade refrigerators and freezers are designed...

This study aims to characterize the hydrogen fuel blending performance (up to 30% blend) of a Robur Gas Absorption Heat Pump (GAHP)-A unit to sufficiently populate model inputs in EnergyPlus. Gas Technology Institute (GTI) Energy will serve as a contractor for this study. They will develop a test...

The existing commercial foodservice (CFS) measures offered in California (CA) incentive programs are the most common pieces of equipment for this industry. Many of these measures will be considered for appliance code standards in the coming years or removed from programs due to the gas incentive...

Central heat pump water heating systems (CHPWH) are crucial for the greenhouse gas, decarbonization, and energy efficiency goals of California. This technology is relevant to a large portion of the multifamily and commercial building market and the earliest adopters are beginning to install these...

Water heating accounts for 40 percent of natural gas consumption in the residential sector, representing 7 percent of the state’s total GHG emissions (E3 2019). Water heating energy use in multifamily buildings with 5 or more units accounts for 32 percent of total energy use based on a 2015...

Standard designs for large commercial buildings rely on separate gas-fired hydronic heating and chilled water loops. This technology has slowly been refined with incremental energy efficiency improvements over several decades. The HVAC industry has not yet had enough time to establish how to serve...

Water heating energy use in multifamily buildings can account for 27 to 32 percent of total energy use based on 2015 Residential Energy Consumption Survey by U.S. EIA. Heat Pump Water Heating (HPWH) systems use electricity to produce hot water by transferring heat energy from one source, typically...
